Gandalf 

1. Sexual Slang – To be rejected in a decisive, almost theatrical fashion, usually when making a sexual advance. Originates from Gandalf’s line in The Lord of the Rings: “You shall not pass.”

2. Gaming Slang – To wipe out enemies in spectacular fashion, shutting them down from advancing.

3. Social – To block someone from access, usually with flair.

Variants:

Mini-Gandalf: partial wipe, still stylish or high body count (gaming)

Full Gandalf: total shut down (social), 100% annihilation (gaming).

Reverse Gandalf: when you try to be clutch but get wrecked instead.

"Bro thought he was smooth but she hit him with the Gandalf — legs crossed, arms folded, denial absolute."

"That triple headshot? Straight Gandalf."

"They almost had Alpha point but Jake pulled a Gandalf."

"Security pulled a Gandalf on me, couldn’t even get near the stage."
